枚举常量概要

枚举常量

枚举常量	说明
STREAM_ACCESSIBILITY	Indicates audio streams used for prompts in terms of accessibility.
STREAM_ALARM	Indicates audio streams for alarms.
STREAM_BLUETOOTH_SCO	Indicates audio streams for voice calls routed through a connected Bluetooth device.
STREAM_DTMF	Indicates audio streams for dual-tone multi-frequency (DTMF) tones.
STREAM_MUSIC	Indicates audio streams for music playback.
STREAM_NOTIFICATION	Indicates audio streams for notifications.
STREAM_RING	Indicates audio streams for ringtones.
STREAM_SYSTEM	Indicates audio streams for system sounds.
STREAM_TTS	Indicates audio streams exclusively transmitted through the speaker (text-to-speech) of a device.
STREAM_VOICE_CALL	Indicates audio streams of voices in calls.

方法概要

限定符和类型	方法	说明
int	getValue()	Obtains an enum value.
static AudioManager.AudioVolumeType	valueOf(String name)	返回带有指定名称的该类型的枚举常量。 字符串必须与用于声明该类型的枚举常量的 标识符完全匹配。(不允许有多余 的空格字符。)
static AudioManager.AudioVolumeType[]	values()	按照声明该枚举类型的常量的顺序, 返回 包含这些常量的数组。该方法可用于迭代 常量, 如下所示: for (AudioManager.AudioVolumeType c : AudioManager.AudioVolumeType.values()) System.out.println(c);

方法详细资料

values

public static AudioManager.AudioVolumeType[] values()

按照声明该枚举类型的常量的顺序, 返回 包含这些常量的数组。该方法可用于迭代 常量, 如下所示:

for (AudioManager.AudioVolumeType c : AudioManager.AudioVolumeType.values())
    System.out.println(c);

返回:

valueOf

public static AudioManager.AudioVolumeType valueOf(String name)

返回带有指定名称的该类型的枚举常量。 字符串必须与用于声明该类型的枚举常量的 标识符完全匹配。(不允许有多余 的空格字符。)

参数:

name - 要返回的枚举常量的名称。

返回:

返回带有指定名称的枚举常量

抛出:

IllegalArgumentException - 如果该枚举类型没有带有指定名称的常量

NullPointerException - 如果参数为空值

getValue
